LUBBICATOR.

T o all whom it may concern:

Be it known that I, CHESTER J. VAN DonnN, a citizen of the United States, residing at Chanute, in the county of Neosho and btate of Kansas, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

This invention relates to. improvements in lubricators; and my object is to provide a device of this character whereby oil may be supplied to a. journal and its bearing without waste.

The device embraces an oil-containing chamber or reservoir having an open end in contact with the journal, so that the oil in said chamber will rest against the revolving journal and constantly keep the same coated with a film of oil. The device also embraces means for forcing the chamber against the journal with any desired degree of pressure, so that the iiow of oil upon the journal may be regulated as required..

Referring now to the accompanying drawing, which illustrates the invention: Figure l represents a vertical longitudinal section on line I-I o-f Fig. 2, of a. bearing provided with my improved holder. Fig. 2 is a vertical cross section of the same on line II-II of Fig. l. Fig. 3 is a horizontal section of the lubricator on line III- III of Fig. l.

l designates the journal which is mounted in a bearing 2 provided with my improved lubricator. Said lubricator comprises an oil-containing chamber or hollow member 3, which is open at both ends so that it may receive oil at one end and discharge it at the other end upon the journal. The discharge end of chamber 3 is concave so as to snugly fit the journal l, against which it is pressed by a coil-spring Il so that the oil will be discharged upon the journal in the form of a film, the thickness of which is regulated by the pressure of the chamber against the journal. By thus regulating the discharge of oil the ournal will be constantly supplied with the required amount thereof, but there will be no waste, because it is impossible for a surplus of oil to flow from the chamber. The upper end of the chamber wall is reduced to form a shoulder for the lower end of coil spring t to abut against.

In order to insure a snug fit between the journal and the chamber, I form a groove Specification of Letters Patent.

in its concave end and fill the same with packing consisting of an annular ring of felt or other suitable material 5.

Chamber 3 is loosely mounted in a case consisting of a hollow body portion or cylinder 6 and a cap 7 both of which are, preferably, composed of sheet metal. The lower end of cylinder 6 is firmly secured in bearing 2, and its upper portion is provided with two diametrically-opposed openings 8, througn which a pair of supplemental coils 9 on the upper portion of the coil spring 4 project. Coils 9 also reliably secure cap 7 in position upon the cylinder, said cap being provided with outwardly-pressed portions 10for the reception of said coils, as shown in Figs. 2 and 3. Portions 10 project from the periphery of the cap, forming handengaging portions where-by the cap may be removed from the cylinder 6.

Having thus described my invention, what I claim is l. The combination with a bearing and a journal mounted therein, of a cylinder a cap for closing the same, an oil-containing chamber in the cylinder having an open end in contact with the journal, and a coilspring pressing against the chamber and provided with supplemental coils which project through the sides of the cylinder and engage the cap to lock the same in place.

2. In combination, an inner hollow body portion, a hollow member having its lower end curved to lit a shaft and tting in the body portion, packing in the lower edge of the inner hollow member, and a spring for normally forcing the inner hollow member downwardly in the body portion.

3. In combination, a cylindrical body portion, an inner hollow member slidably mounted in said body portion and having its lower edge concaved to fit a shaft, packing in the lower edge of said hollow member, a shoulder formed on the inner member, and a coiled spring secured to the cylindrical portion and bearing on the inner member to force it downwardly.

4;. In an oil cup for a bearing, the combination with a cylindrical body portion formed with openings, an inner hollow member fitting within the cylindrical body portion and having its lower end concaved to t a shaft and its upper edge reduced to form a shoulder, a packing tting in a groove formed around the ooncaved edge of the inner ineinber, and a coiled spring bearing on the shoulder, said spring having a bent portion and an extension to engage the openings in the body portion.

5. The combination wtli a. bearing and a journal mounted therein, of a case Coniinunicating with said bearing having peripheral openings, a cap for closing the upper end of said oase having peripheral project-ions adapted to register with the openings in the Case, an oil-containing chamber in the ease having an open end in Contact with the Journal, and a coil spring pressing downward on said oil-containing 15 chamber and extending through the peripheral openings in the ense to engage the projections on the cap.

In testimony whereof I aiix iny signature, in the presence of two witnesses.
